5. “We’re surrounded. That simplifies things.” Marines are the heirs to the relentless grit and courage of Lewis “Chesty” Puller, who as a colonel led his forces in inflicting huge casualties against the encircling Chinese forces in the Battle of Chosin Reservoir, for which he received his fifth Navy Cross. He retired as a lieutenant general and the most decorated Marine in history.

7. On Nov. 13, 2004, then 1st Sgt. Bradley Kasal fought to clear Fallujah's infamous “House of Hell” and rescue Marines trapped inside. He was shot seven times by insurgents and took shrapnel when he used his body to protect a wounded Marine from a grenade blast. A picture of him with two Marines helping to carry him out of the house became one of the most iconic pictures from the Iraq war. Now a sergeant major, Kasal received the Navy Cross in 2006.

10. “Are you allowed to eat jelly doughnuts, Pvt. Pyle?” When retired Gunnery Sgt. R. Lee Ermey played the drill instructor in “Full Metal Jacket,” he inspired countless Marines to see if they are tough enough to make it through recruit training. The movie and his performance are indelible parts of Corps lore.
